Thetford toilet fresh up set

Hi,
I have a Thetford toilet fresh up set for sale, I bought this for my 2004 Autotrail tracker, but decided to change vans before I fitted it, it is for the C2-C3 or C4 series toilet, it consists of Holding tank cassette, seat and cover, + cleaning agents. It is brand new and unused in the box I bought it in. Too large for me to post so buyer must collect.
The retail price is £99-00 , I would like £ 60-00 if anyone is interested.
